Turn delivery evidence into
defensible invoices automatically.

Yes. Effigate natively supports Fixed Price, Hourly, Bucket-Based, and Scope-Based contract types. Each model has distinct billing rules enforced by the platform — Fixed Price ties invoicing to milestone completion, Hourly converts approved time logs into billable records, Bucket-Based tracks prepaid hour consumption per job type category, and Scope-Based triggers billing on deliverable sign-off. The contract type is locked at activation so the commercial model cannot drift over the engagement lifecycle.

Yes. When SLA breaches carry contractual financial consequences, Effigate connects breach evidence from the SLA engine directly to billing deduction line items. Each breach record carries a timestamp, duration, severity classification, and contract reference. Deduction line items are generated from this structured evidence and applied at the contracted deduction schedule — no manual finance reconciliation step is required. The client portal surfaces the full SLA timeline and deduction calculation detail, and the finance team retains a complete audit trail for any credit dispute.

Once an invoice is issued in Effigate, it is frozen. The commercial record cannot be silently modified after it has been sent to a client. This protects audit integrity, prevents accidental or unauthorised changes to agreed billing, and ensures that the invoice history accurately reflects what was communicated. If a correction is genuinely required, the platform enforces an explicit corrective action — such as issuing a credit note or an amended invoice — so there is always a clear, traceable record of any change to the original billing position.

Bucket-Based contracts are prepaid hour arrangements where clients purchase a block of hours (for example, 50h, 75h, or 100h) that the delivery team draws down through tickets and tasks. The bucket size and the number of allowed job type categories are independently configurable — there is no hard-coded link between the two. Every time a time log is recorded against the contract, the remaining balance decreases in real time. Both the delivery team and the client (via the client portal) can see the current balance. Low-balance alerts fire before the bucket exhausts, and a formal amendment workflow governs any request for additional hours.

Rate cards in Effigate support multiple billing conditions beyond the standard rate: weekend work, after-hours delivery, priority-level surcharges, additional hours beyond scope, and multi-tier support levels (L1, L2, L3, Solution Architect). When a contract activates, the applicable rate card is frozen — subsequent changes to the rate card library do not affect active engagements. Each condition is evaluated per time log and applied automatically at invoice assembly. The full rate audit trail is retained, showing the original agreed pricing across the entire invoice history for any commercial review or dispute.
