What it means

Most of your third-party spend is somebody's billable cost

Procurement outsourcing for a professional services firm means an outside team runs supplier and subcontractor operations — invoice capture and coding to engagement, rate-card and contract checks, client reimbursable and disbursement handling, supplier onboarding and accounts payable — while partners keep the client relationship and every approval stays with you.

In a consultancy, an engineering practice or an agency, third-party spend is not mostly overhead. It is associates, specialist subcontractors, travel and pass-through costs, and a large share of it is recharged to a client under a contract that caps rates, requires coach fares, sets per-diem limits and may or may not allow a mark-up. One subcontractor invoice can carry billable project work, non-billable rework and travel on the same document.

Get the coding wrong and you do not just lose margin — you produce a client invoice that gets queried, and cash slips a month. We run that work: coded to the engagement, checked against the contract, ready to recharge.

What never moves

Client relationships, scoping and pricing stay with your partners. We do not talk to your clients, and every approval and payment release stays inside your firm.

The problem

Where firms lose money on cost they already agreed to

Six failure modes we see across consultancies, agencies and engineering practices. Most of them are coding problems, not sourcing problems.

  • Invoice coded to the correct engagement
    01

    Costs coded to the wrong engagement

    A subcontractor invoice lands against the practice rather than the project, and the recharge never happens at all.

    Invoice processing
  • Mixed invoice being split line by line
    02

    Mixed invoices treated as one thing

    Billable work, non-billable rework and travel on one document, coded whole because splitting it takes an hour.

    Invoice processing
  • Subcontractor rate checked against the contract
    03

    Rate cards nobody checks against

    The associate billed a grade above the contract, and the difference is only found if someone opens the agreement.

    Master data management
  • Client disbursements tracked to the submission deadline
    04

    Disbursements that never get recovered

    Receipts arrive late, past the client's submission window, and a recoverable cost quietly becomes an absorbed one.

    F&A operations
  • Associate compliance documents being collected
    05

    Associates onboarded ad hoc

    Insurance, right-to-work, NDAs and IR35-style status checks chased by whoever hired them, or not chased at all.

    Master data management
  • Spend across practices classified into one view
    06

    No view of what a practice actually buys

    Spend sits in project codes, so the fifteen suppliers used across four offices never appear as one negotiation.

The evidence

What the numbers say

Published benchmarks for the invoice work underneath every engagement. We have no client results yet and will not invent any.

Published industry benchmarks, not our results — we are a new firm and say so. The free audit measures your own numbers, so the comparison is real rather than borrowed.

How it starts

Four to six weeks, and a pilot before any commitment

If the pilot does not beat the baseline we measured, you have a report and no contract.

  1. Transaction history prepared for the free spend audit
    01

    Free spend audit

    We measure what you have today across practices and offices — spend, supplier count, volumes, cycle times.

    • Spend cut by practice and category
    • Requisition, PO and invoice volumes
    • Written baseline, yours to keep
  2. Client lead named as the single point of contact for the pilot
    02

    Fixed-fee pilot

    One practice, or one category. Real transactions, scoped access, criteria agreed in writing first.

    • Process and SOPs documented
    • System access under your controls
    • Measured against the baseline
  3. Monthly SLA and savings reporting
    03

    Embed and widen

    Named analysts move to steady state, then scope widens practice by practice at your pace.

    • Named analysts, named cover
    • Monthly SLA and savings reporting
    • Volume flexes without rehiring

Hiring, us, or your practice management software

Where each option wins. If your subcontractor volume is low and one finance manager already sees every invoice, keep it there — we will say so on the first call.

Questions

Frequently asked questions

What finance, operations and practice leads ask before an engagement starts.

Ask us anything
What does procurement outsourcing mean for a professional services firm?

An outside team runs supplier and subcontractor operations: invoice capture and coding to the right engagement, rate-card and contract checks, client reimbursable and disbursement handling, associate and supplier onboarding, purchase orders and accounts payable. Client relationships, scoping and pricing stay with your partners, and every approval stays inside your firm.

Will you ever contact our clients?

No. We work behind the firm, not in front of it. We prepare what a recharge needs — coded costs, receipts, contract references — and your team sends it. Your clients do not know we exist unless you choose to tell them.

Can you split a subcontractor invoice across billable and non-billable lines?

Yes, and it is the single most valuable thing we do here. One invoice can carry billable project work, non-billable rework and travel. We split it by line, code each part to the right engagement and cost type, and flag anything that looks recoverable but is missing the evidence a client will ask for.

How do you check subcontractor rates against our contracts?

Rate cards are held as data against each supplier and engagement — grade, rate, effective dates, any cap or mark-up rule. Every line is checked against them before approval routing, and a breach becomes an exception with the contract reference attached, so the conversation with the supplier is factual rather than approximate.

Can you handle client reimbursable and per-diem rules?

Yes. Rules vary by client contract — coach airfare only, per-diem caps, no mark-up on pass-through, receipts required above a threshold — and we hold them per client rather than as one firm-wide policy. Costs that breach a rule are flagged before they reach a client invoice rather than after it is queried.

How do you make sure disbursements actually get recovered?

By working the deadline rather than the receipt. Recoverable costs are tracked against each client's submission window, chased before it closes, and reported weekly with anything at risk of falling outside it. Most unrecovered disbursement is not disputed — it is simply late.

Can you help with associate onboarding and compliance checks?

Yes: insurance certificates, right-to-work, NDAs, conflict checks and employment-status documentation collected, filed where your auditors expect them, and diarised for renewal. We collect and chase; your team makes every status determination, because that is a legal judgement and not an administrative one.

How much does procurement outsourcing cost?

Either a price per transaction — per invoice, expense claim or purchase order — or a monthly fee for a dedicated analyst. Both models are on the table from the first call. We quote after the free audit, because the honest number depends on your volumes, your systems and how many transactions need exception work. Anyone quoting before seeing that is guessing.

How do we know it is worth it?

Compare your fully loaded cost per invoice, expense claim or purchase order against the quote. Fully loaded means salaries, benefits, overhead, software and the hours your finance and practice staff spend chasing. The free audit measures your current figure, so the comparison is your number against ours rather than a benchmark against a brochure.

What is not included in the price?

We say up front rather than at renewal. Setup and process documentation sit inside the fixed-fee pilot. Ongoing fees cover the agreed scope and volume band. Anything outside it — a new entity, a new system, a large one-off backlog — is quoted separately before work starts.

How long does it take to start?

Four to six weeks from first conversation to a team running live work. Roughly two weeks for the audit, then a fixed-fee pilot, then steady state. Your side of the work is a data extract, one named contact, scoped system access and your approval rules.

Which systems do you work in?

NetSuite, Deltek, Sage Intacct, Xero, QuickBooks, Certinia and Kantata, plus the time-and-expense systems alongside them. We work inside your system rather than asking your team to learn ours, so there is no migration and no new licence. Where you run more than one — usually after an acquisition — we work in each and map both to one classification for group reporting.

Is it safe to give an offshore team access to our data?

Access is scoped by you, granted to named individuals and revoked through your own leaver process. We contract on standard clauses, name every sub-processor, and work to GDPR, UK GDPR, PIPEDA, the Australian Privacy Principles and Saudi PDPL. ISO 27001 alignment is in progress and SOC 2 Type II is on the roadmap. We state certification status as it is rather than showing badges we do not hold.

Where is our data processed, and can we keep it in-region?

Delivery is from India and the Middle East, and we say so plainly rather than burying it. Your data stays in your systems — we work inside them rather than copying data out. Where a copy is unavoidable, the storage region is written into the DPA, and we support UK IDTA and EU standard contractual clauses for transfers to India.

What certifications should we ask any provider for?

ISO 27001 or SOC 2 Type II, then two follow-up questions most providers dodge: which legal entity is certified, and what the audit scope actually covers. A badge on a website tells you nothing without those two answers. Ask us the same questions.

How do you prevent supplier fraud and duplicate payments?

Duplicate detection runs before approval routing. Any change to a supplier's bank details is treated as an exception, never actioned by us, and escalated to your nominated contact for out-of-band verification. The analyst who maintains supplier master data is never the analyst who processes that supplier's invoices.

Will we lose control of approvals and payments?

No. We prepare and route; you approve and release. Nobody on our side can move money or authorise a payment, and your delegation of authority stays exactly as it is.

Do we get a dedicated team or a shared pool?

Named analysts assigned to your account, with named backup cover for leave and absence. You know who does the work and who to call. Cover is a contractual term, not something you find out about when someone is on holiday.

What are the SLAs, and what happens if you miss them?

Turnaround time, accuracy and exception-closure rates are agreed during the pilot against your measured baseline, then reported monthly. Remedies for a sustained miss are written into the contract rather than left to goodwill, and either side can exit on notice if the numbers do not hold.

What happens to our own team?

Most clients redeploy them onto engagement profitability, panel negotiation and the recovery work nobody has time for rather than cutting headcount. We will tell you honestly what your volume supports instead of promising a headcount number to win the work.

What if we want to bring it back in-house?

You keep the SOPs and process documentation, because they are yours throughout, and your data never leaves your systems. Transition-out support is written into the contract from day one rather than negotiated at the point you want to leave.

When is outsourcing the wrong answer for us?

When your subcontractor volume is low enough that one finance manager sees every invoice, or when nearly all your cost is payroll rather than third party. We will say so on the first call. A pilot that fails costs us more than a deal we decline.

What exactly does the free spend audit measure?

Subcontractor and supplier invoice volumes, how much is coded to the right engagement, rate-card exceptions, and disbursements recovered against those written off. You get a written baseline you keep whether or not you go further, and it is the number every later comparison is made against — including ours.
