What it is
A bill rate is the hourly or daily amount a staffing agency invoices a client for a contractor's time on assignment. It is the client-facing price point, the number that appears on the timesheet-driven invoice, and it sits above two other figures that are often confused with it: the pay rate, what the contractor actually receives, and the margin, what the agency keeps after employer costs. If a contractor is paid £40 an hour and the agency bills the client £56 an hour, £56 is the bill rate, £40 is the pay rate, and the £16 spread, before deductions, is where markup and margin live.
Bill rate is usually fixed in advance rather than negotiated per assignment. On a single bilateral account it is agreed as part of terms of business. On an enterprise programme run through an MSP or VMS, it is published in a rate card by role, seniority and location, and every supplier on the panel quotes within it. Either way, the bill rate is the one number a client sees before they ever see a CV, which makes it the first thing that decides whether a submission is even considered.
Bill rate is what the client pays. Pay rate is what the contractor earns. Confuse the two and you cannot tell if a placement is actually profitable.
Why it matters
Bill rate is a competitive variable, not just a pricing mechanic. On a VMS-managed requisition, procurement can see every supplier's submission at a glance, so a bill rate that is out of line with the rate card, even by a small margin, can knock a strong candidate out before anyone reads the CV. Quote too high and you lose the submission. Quote too low and you have underwritten the placement for the length of the contract, because a bill rate agreed in week one is the bill rate charged in week twenty.
It also carries risk the moment the underlying rules change. A role's IR35 status moving between inside and outside determinations, or a rate card that has not been reviewed since it was signed, can leave a bill rate quietly wrong, either uncompetitive against the market or too thin to cover the deductions that now sit inside it. None of that shows up as a single dramatic error. It shows up as a desk that keeps billing but keeps less of it than the rate card implies.
How boilr handles it
boilr does not set your bill rates, that stays a commercial negotiation between your agency and the client. What it does is make sure the agreed rate, and the rate card or terms of business it comes from, is never buried in an old email or left in one consultant's head. Once a bill rate exists for an account, it lives in the Company Brain alongside that account's pay rate markup, margin bands and IR35 context, so any consultant picking up the requirement quotes from the same number.
When a hiring signal fires on a contract or temp account, your AI sales employee already has the agreed bill rate context attached, so the task it drafts references a figure that reflects what the desk actually agreed, not a guess reconstructed from memory. Because that context survives a consultant leaving, the desk always has something concrete to check before a submission goes out, instead of relearning the account's pricing from scratch.
