- Where does the knowledge live?Build continuity around a team, with prepared backup.
- What happens after go-live?Keep support affordable through stabilisation and BAU.
In this article
Comparing contractor costs vs embedded delivery starts with day rates. The wider decision is how to fund the capacity, quality and continuity needed to deliver change and sustain it.
In a Source-to-Pay (S2P) transformation, employees may be expected to prepare data, test a platform and keep procurement running. Budget pressure can then remove knowledgeable project colleagues just as users need help adopting the new processes.
A stronger mix of delivery models
Embedded delivery can accompany existing employees, contractors and implementation partners. Contractors may provide scarce platform expertise or interim leadership; implementation partners may own technical delivery; Denova colleagues add analysis, coordination, data and operational capacity around those responsibilities.
In our embedded delivery model, the client directs daily priorities while Denova manages employment, training and ongoing support. With a managed service, Denova manages defined activities against agreed responsibilities and measures.

01 / The cost of capacity
UK contractor day rates compared with embedded delivery
A median is the middle advertised rate in the sample. The table uses IT Jobs Watch medians and Denova’s public indicative bands.
Read this as a budget comparison. Advertised UK contractor rates are compared with Philippine-based remote embedded delivery. Equal billable days do not establish equal skills, responsibilities or output.
| Role / market source | UK contractor median | Denova indicative band | Daily difference | Lower than median |
|---|---|---|---|---|
| Business Analyst | £500 | £200–£250 | £250–£300 | 50.0–60.0% |
| Change Analyst | £501 | £150–£200 | £301–£351 | 60.1–70.1% |
| Project Manager | £538 | £200–£250 | £288–£338 | 53.5–62.8% |
| PMO Analyst | £370 | £150–£200 | £170–£220 | 45.9–59.5% |
| Data Analyst | £450 | £150–£200 | £250–£300 | 55.6–66.7% |
| Power BI Developer | £452 | £200–£250 | £202–£252 | 44.7–55.8% |
| Data Engineer | £501 | £200–£250 | £251–£301 | 50.1–60.1% |
| Application Support Analyst | £400 | £150–£200 | £200–£250 | 50.0–62.5% |
Denova bands: public rate calculator, checked 6 October 2026. All differences use the displayed rates and equal billable days. On a small screen, scroll the tables sideways.
For a Business Analyst, the displayed difference is £250–£300 per day. Across 100 billable days, that would release £25,000–£30,000 of gross budget capacity, before any differences in scope, additional charges or client effort.
How to read the benchmarks and their limits
IT Jobs Watch reports six-month UK vacancy data. Daily-rate quote counts and period end dates used here are: Business Analyst 1,352 (5 October 2026); Change Analyst 31 (5 October); Project Manager 1,242 (5 October); PMO Analyst 75 (30 September); Data Analyst 475 (5 October); Power BI Developer 70 (3 October); Data Engineer 1,247 (5 October); Application Support Analyst 19 (2 October). Smaller samples are less robust.
These are advertised IT contractor rates across mixed seniority, locations and engagement terms, not observed invoices or specialist S2P implementation rates. Denova’s indicative bands are not a market median or a binding offer. Confirm skill level, scope, working hours, location, access and availability. Remote delivery from the Philippines is not identical to buying an on-site UK contractor.
Examples exclude VAT, travel, expenses and any additional charges. No assumed agency margin, employer cost or IR35 uplift has been added. Compare actual all-in commercial terms before committing a budget. Rate differences do not establish equal productivity or guarantee realised savings.
02 / A practical S2P example
What changes when selected project roles use embedded delivery?
Consider four roles within an S2P programme. Keep their planned effort unchanged and compare programme-specific embedded rates with the public UK medians above. This shows the potential effect of changing selected roles without replacing the whole delivery team.
| Programme role | Days | Embedded rate / day | Embedded cost | Market benchmark cost | Difference |
|---|---|---|---|---|---|
| Project management, cutover and hypercare | 285 | £250 | £71,250 | £153,330 | £82,080 |
| Business analysis | 220 | £200 | £44,000 | £110,000 | £66,000 |
| Change support | 130 | £170 | £22,100 | £65,130 | £43,030 |
| Data and supplier enablement analysis | 123 | £150 | £18,450 | £55,350 | £36,900 |
| Total | 758 | — | £155,800 | £383,810 | £228,010 |
£228,010
Illustrative gross difference across the selected roles.
59.4%
Lower than the mapped contractor benchmark cost.
758 days
The same planned effort on both sides of the comparison.
Illustrative, anonymised comparison using Denova rates of £150–£250/day within the published bands. Contractor costs use planned days × role medians. Data Analyst, Project Manager and Change Analyst are broad benchmarks; scope and seniority require validation.
Figures are not achieved client savings or whole-programme savings.
A smaller starting point: three support roles
Assume 60 billable days each of data analysis, PMO and application support: 180 person-days in total. Using the public medians and £200 per day for each embedded role gives three options.
| Option | Resourcing assumption | Total cost | Difference |
|---|---|---|---|
| Contractor benchmark | Data £450, PMO £370, application support £400 per day | £73,200 | — |
| Mixed delivery | Data contractor at £450; embedded PMO and application support at £200 | £51,000 | £22,200 |
| Embedded support | All three suitable roles at £200 per day | £36,000 | £37,200 |
The mixed option retains a data contractor while adding embedded PMO and application support, releasing £22,200 of illustrative budget capacity.
03 / Build confidence through delivery
Start with bounded work, then expand as trust grows
Our longer-term client relationships have grown from small engagements into more specialist work as delivery builds trust and business knowledge. That gives clients a practical route to explore further savings.
Within procurement transformation, the activities below offer clearly reviewable starting points. Their lower risk comes from defined outputs, controls and decision rights; they still require suitable skills.
| Activity | A bounded starting scope | Control retained by the client |
|---|---|---|
| Data preparation | Profile records, identify duplicates, prepare exceptions and cleanse an agreed dataset. | Approve rules and production changes; retain ownership of sensitive master data. |
| Testing and PMO | Coordinate UAT, maintain evidence, track defects and follow up actions. | Approve acceptance criteria, risk decisions and go-live readiness. |
| Supplier enablement and change | Track onboarding, prepare guidance and coordinate training and communications. | Approve messages, policy and supplier commitments. |
| Process and business analysis | Document agreed processes, capture requirements and organise validation. | Make design decisions and accept requirements and deliverables. |
A practical first engagement has named outputs, an accessible process owner, approved access and a review point. Measure accuracy, turnaround, rework and the client time needed to support delivery. Expand the scope when that evidence supports it, including specialist work where the team’s capability has been demonstrated.
These activities should sit within the procurement transformation roadmap, with dependencies and operational capacity made explicit.
04 / Continuity built around a team
The ace up our sleeve: the shadow buddy model
A critical role becomes a single point of failure when only one person understands its processes, system quirks or unresolved issues. That dependency can affect permanent employees, contractors and embedded colleagues alike.
For agreed roles, Denova embeds a backup colleague to shadow the primary team member and learn the work before cover is needed. The model’s superpower is shared context: someone familiar with the processes, stakeholders and current issues has a stronger starting point for supporting an absence or transition. This prepares continuity beyond an individual assignment.
1. Learn alongside
Build familiarity with the agreed work, recurring tasks, stakeholders and exceptions while the primary colleague is delivering.
2. Keep context current
Use shared documentation and an agreed shadowing rhythm so cover reflects how the work operates today.
3. Step in with a plan
Agree the cover scope, access, decision rights and escalation route before the arrangement is needed.
Agree the scope and readiness of cover, authorised access and the handover plan. Available capacity and responsibilities still need to be defined.
Shadow buddies in practice: procurement and supplier relationship management
At a major UK financial services organisation, Denova supports S2P operations and supplier relationship management. For selected roles, backup colleagues learn the work alongside the primary team member, preparing to take on agreed responsibilities if cover is needed.
The case study reports reduced reliance on individuals and greater reassurance about continuity, while helping avoid permanent duplication of roles solely for cover. The benefit is preparation: someone understands the work before an absence or departure creates a gap. Read the procurement and supplier relationship management case study.
05 / Keep the business moving
Protect BAU while change is ongoing
One of the most common capacity problems is a circular one. A business-as-usual (BAU) colleague is allocated to the project because they understand the operation. An urgent operational issue then pulls them back. Workshops move, testing slips and the improvement that would reduce the workload is delayed.
Embedded colleagues can support the project directly or take on suitable BAU activity while internal experts contribute to change. Examples include supplier enquiries, system administration, reporting, data-quality checks and issue coordination. The useful outcome is protected capacity on both sides.
That protection needs an explicit allocation of work. Agree which priorities take precedence, who handles urgent demand and what triggers extra support. Adding a person without agreeing these boundaries can reproduce the same conflict.
Make stabilisation affordable and support the targeted ROI
Go-live changes the nature of the work. Users need help, exceptions emerge, reporting needs refinement and operational owners need confidence. Yet this is often when pressure to release expensive project resources is strongest.
Lower ongoing delivery costs reduce the financial incentive to roll off knowledgeable team members immediately after implementation. The colleagues who helped prepare data, test processes and support users can remain through a stronger stabilisation period, carrying their understanding into BAU and continuous improvement.
| Stabilisation support | At contractor median | Embedded at £200/day | Difference |
|---|---|---|---|
| Data Analyst · 40 days | £18,000 | £8,000 | £10,000 |
| Application Support Analyst · 40 days | £16,000 | £8,000 | £8,000 |
| Total · 80 person-days | £34,000 | £16,000 | £18,000 |
The £18,000 difference could reduce spend or fund further agreed support. It cannot be counted as both a cash saving and money reinvested.
Continuity in practice: stabilising AP through a staffing transition
When a key accounts payable colleague departed from a global organisation, the team faced more than 200 unresolved tickets and only one day of knowledge transfer. Denova provided an embedded AP specialist while the client recruited a permanent replacement.
As reported in our case study, the specialist cleared the backlog and left the incoming employee a stable, documented process. This illustrates how embedded cover can resolve immediate operational pressures and prepare the next person to take ownership. Read the accounts payable case study.
For an S2P programme, assess retained support through supplier onboarding, exception backlogs, invoice accuracy, process adoption and support demand. Compare results with an agreed baseline and assign a business owner to each benefit. Affordable continuity can enable the targeted ROI; operational results show whether it is being achieved.
06 / Evaluate the support around the person
Quality, attrition and compliance belong in the comparison
Strong contractors can deliver excellent work. The concern is the amount of recruitment, quality assurance and continuity planning that can remain with the client when each assignment is managed separately. Embedded delivery provides an ongoing support structure, but its value still depends on how that structure is put into practice.
| Potential pressure in individual contractor arrangements | How embedded delivery can help | What to agree or check |
|---|---|---|
| Quality varies and the client carries the assessment burden. | Denova recruitment, training, mentoring and performance management support the colleague throughout the engagement. | Role fit, acceptance criteria, review cadence and how issues will be corrected. |
| Attrition or an assignment ending can trigger new sourcing and onboarding. | Ongoing employment and team support provide a basis for continuity; shadow buddies prepare cover for agreed roles. | Cover readiness, access, transition arrangements and escalation ownership. |
| Knowledge becomes concentrated in one person. | Shared context, shadowing and continuing support help retain knowledge beyond an individual assignment. | Current documentation, client access to it and a tested handover approach. |
| High day rates make continued post-project support harder to justify. | Lower costs for suitable work make stabilisation and ongoing improvement easier to fund. | Actual scope, billable days, additional charges and measurable support outcomes. |
| Multiple arrangements create onboarding and compliance administration. | Denova manages its colleagues’ employment and development within an agreed supplier relationship. | Contract terms, data protection, authorised access and responsibilities across the supply chain. |
07 / Evidence from longer-term relationships
How support grows alongside the existing team
Our published client stories illustrate how embedded support develops across recurring operations and specialist priorities.
UK financial services
Capacity with prepared cover
Across an engagement approaching two years at the time of the case study, support included S2P administration, supplier management, improvement work and extra capacity around quarter-end. Shadow buddies prepared cover for selected roles.
Global pharmaceutical
Capability that develops over time
An approximately two-year relationship combined recurring finance and commercial reporting with dashboards, automation, data cleansing and transformation support. Client knowledge and Denova’s development support grew alongside delivery.
Global cyber security
Knowledge through changing needs
Support moved across procurement, Zip and accounts payable. Colleagues returned after a budget pause with knowledge of the business, while the engagement also used shadow-buddy cover. Future availability must still be agreed.
Compare the whole delivery decision
Define the work, the skills it needs, the decisions retained by your team and the support required after implementation. Compare the full commercial terms and client effort alongside day rates, including the cost of disruption, rework and repeated onboarding.
The aim is an affordable team with the capability and continuity to deliver change and sustain its benefits.
