Invoice Finance vs R&D Tax Credit Advance
Invoice finance and R&D tax credit advances are different products that release cash from different sources. Invoice finance advances cash against unpaid B2B invoices (ongoing, 24hr, 0.5-3%). R&D tax credit advance releases cash from pending HMRC R&D claims (annual, part of the expected claim advanced). They can be used at the same time. HMRC's own figures show most R&D claims are processed within 40 days (HMRC, 2023 to 2024), so an R&D advance mainly helps with large or delayed claims.
Use invoice finance for the ongoing gap between invoicing and payment; use an R&D advance for the once-a-year wait on an HMRC claim. More detail + scope
