Deliverable approval delays push T&M invoices
Time-and-materials invoices require client sign-off on hours logged. Approval delays of 1–2 weeks on every invoice create a compounding receivables gap.
SparkCashFlowRequest SprintCash Flow for Engineering Consultancies
Milestone billing and T&M invoicing never line up with weekly payroll. Map the gap.
Engineering consultancies carry significant staff costs against project-based billing that depends on deliverable completion and client approval. The Sprint maps your active project billing schedule against your weekly overhead so cash timing is explicit.
- 13-week cash map
- 3 what-if scenarios: delayed milestone, project pause, cash bridge
- 72-hour delivery — pay nothing if it's late
- 5-min weekly update — yours to run
Proposal and pre-project work is uncompensated
Engineering proposals require significant technical work before any fee is paid. That unbillable time has a real cash cost the Sprint accounts for.
Equipment and subcontractor costs precede billing
Instrumentation, testing equipment, and subcontractor costs are incurred before milestone invoices are issued. The Sprint maps those advance costs explicitly.
Best fit
Engineering consultancies with 3–30 staff using QuickBooks Online or Xero, with T&M, milestone, or retainer billing.

Can the model track government contract billing separately?
Yes. Government contracts with their specific invoicing and approval cycles are mapped separately from commercial work in the model.
What about retainage withheld on construction projects?
Retainage is tracked as a separate receivable line in the model, reflecting when it's expected to be released rather than when the underlying work was billed.
