Rimilia no longer exists as a product, and people still search for it every month. If you shortlisted cash application software at any point in the last decade you'll have met it: a UK company that matched incoming customer payments to open invoices with machine learning, years before that became a standard claim. BlackLine bought it, folded it into an enterprise suite and retired the name, but the searches carried on, and a fair share of the people still typing it run their business on Xero or QuickBooks Online rather than SAP, which is who this post is for.
If you want a current shortlist rather than the history, our guide to the best cash application software covers nine vendors, grouped by ledger and by how much of the receivables job each one takes on.
What Rimilia was, and why AR teams rated it
Rimilia was built around cash application, reading incoming payments and remittance data, working out with machine learning which invoices each payment covered, applying the cash, and leaving a person only the exceptions. For a receivables team sitting on a pile of unapplied cash it was the first proof that the matching step could be handed to software, and matching is the expensive part.
Cash application never got much attention inside receivables. Collections gets the attention, but a payment that has arrived and hasn't been applied causes its own trouble, because the bank balance looks healthy while the ledger goes on chasing customers for money they've already sent. Rimilia built its business on that gap, and built it for large organizations with their own AR departments, payment files arriving from a bank keying service, and an ERP as the ledger of record.
The BlackLine acquisition, and the move upstream
BlackLine bought Rimilia in October 2020 for about $150 million, $120 million at close and up to $30 million more in earnouts, and the fit was straightforward, since BlackLine sells financial close automation to large enterprises, Rimilia extended that into accounts receivable, and both sell to the controller's office at a big company.
What was Rimilia is now BlackLine Cash Application, one module in BlackLine's invoice-to-cash suite next to collections, credit, and dispute management. The technology carried over, it's just sold as part of a platform now, implemented as a program, and aimed at global businesses consolidating payment data across regions, banks and several ERPs at once.
For a global enterprise on SAP or Oracle, BlackLine's suite belongs on the shortlist alongside HighRadius and Billtrust. The market underneath it changed, though, because the one dedicated cash application specialist went up into the enterprise tier and the businesses below it were left without a product aimed at them.
The gap the acquisition left
How much work cash application is depends on the remittances rather than the size of the business. A wholesaler with eight staff gets the same hundred-line supermarket remittance as a listed company, and an NDIS provider with a handful of staff gets bulk government remittances with more lines than most corporates ever see.
The software, though, followed the big companies. Every cash application product on the market assumed payment files from a bank remittance processing service, an ERP as the system of record, a six-figure implementation and an AR operations team to run it, which left teams on cloud ledgers matching by hand, building spreadsheet macros or adding offshore headcount. We've written before about when an offshore AR team stops paying for itself, and it stops at about the volume where the matching starts to hurt. What did reach cloud ledgers was software for the other half of the job, because AR automation covers two separate jobs and the tools that arrived first were the ones that chase the money rather than apply it.
You can see the split in who searches for the name. Some are enterprise buyers who end up at BlackLine, which is the right place for them, and plenty are finance managers and bookkeepers who heard the name, have the problem it solved, and never had an ERP for an enterprise suite to plug into.
Cash application when your ledger is Xero or QuickBooks Online
The useful dividing line in this market is the ledger. We work with two-person bookkeeping operations and with multi-entity groups reconciling remittances across eight Xero organizations, and those two have more in common with each other than either has with an SAP shop. Remittances come straight from the customer as a PDF, a spreadsheet or the body of an email, the cloud ledger itself is the record they get applied to, and the person applying them is usually also running credit control and closing the month.
So what you need looks different from what Rimilia's buyers were specifying:
- Native ledger connection. Rimilia sat between the bank file and the ERP. On a cloud ledger there's nothing to sit between, so the tool has to talk to Xero or QuickBooks Online itself, read the open invoices and write the payment back across every invoice it covers, with the bank feed reconciling as it always has.
- Remittance-driven matching. Rimilia was fed keyed payment files. Yours arrive as whatever your customer's system prints, a supermarket PDF one day and a government CSV the next, and the tool has to read each of those as it is, since your customers won't change their formats for you.
- Exception-only review. This is the part Rimilia got right and it hasn't changed. The routine lines, 99 percent of a standard remittance, apply on their own, and a person only sees the deductions, short-pays and references the tool couldn't place.
- Priced like SaaS, live in days. Products of Rimilia's era were implemented as projects because there was an ERP to integrate with. Connecting a cloud ledger takes a couple of minutes, so you should be matching your first remittance the same day you sign up, on a monthly subscription.
The numbers a small team should watch while it does this, unapplied cash and DSO among them, are in cash application for a small Xero AR team.
RemitClear and BlackLine Cash Application, side by side
Both apply incoming customer payments to open invoices. The differences are the ledger underneath, what each one reads, and what it takes to get live. The BlackLine column uses its own product pages and the acquisition history above, checked September 21, 2026.
| Dimension | RemitClear | BlackLine Cash Application (ex-Rimilia) |
|---|---|---|
| Ledger | Xero and QuickBooks Online, connected directly | ERPs such as SAP and Oracle; BlackLine describes integration with nearly all ERP systems |
| What it reads | Remittance advices as they arrive: PDF, Word, Excel, CSV and email text, with no templates to set up | Customer payment data in any format, consolidated from banks and ERPs across regions, with or without a remittance |
| Getting live | Connect Xero or QuickBooks Online and match the first remittance the same day | An implementation program: integrating with your ERP and configuring payment application rules, guided by BlackLine's team |
| Scope | Matching and posting, with the original remittance kept against the payment for audit | One module of the BlackLine Invoice-to-Cash suite, alongside eInvoicing, collections, credit and risk, disputes and deductions, and AR intelligence |
| Who runs it | A finance manager or bookkeeper, alongside their other work | A dedicated accounts receivable team inside an enterprise finance function |
| Commercials | Monthly SaaS subscription | Enterprise contract arranged through a demo; no pricing published |
Where RemitClear fits
RemitClear does for a cloud ledger what Rimilia did for an ERP. Send it the remittance advice in whatever form the customer used, PDF, Word, Excel, CSV or the body of an email, and it matches each line to your open invoices and posts the payment straight into Xero or QuickBooks Online with the original document kept for audit. It covers the matching and the posting, connecting a ledger takes minutes, and it's in production today for single bookkeepers and for groups reconciling across several Xero organizations, certified by Xero and rated 5.0 on the Xero App Store.
How the same engine behaves on Xero versus QuickBooks Online is covered on our cash application automation page.
Questions people still ask about Rimilia
Is Rimilia still available as a standalone product?
No. BlackLine acquired Rimilia in October 2020 and the technology now sells as BlackLine Cash Application, one module of the BlackLine Invoice-to-Cash suite. There's no separate Rimilia product to buy, and the Rimilia brand has been retired.
What do teams on Xero or QuickBooks Online use instead?
A tool that connects to the cloud ledger directly rather than through an ERP. RemitClear reads the remittance advice your customer sent, matches each line to the open invoices in Xero or QuickBooks Online, and posts the payment applied across them, so the bank feed reconciles without anyone re-keying the advice.
Does cash application automation need an ERP?
No. The enterprise products assume one because their buyers run SAP or Oracle, and BlackLine describes its own onboarding as integrating with your existing ERP. On a cloud ledger the ledger is the system of record, so the automation reads the remittance and writes the payment straight into Xero or QuickBooks Online.
Summary
On SAP or Oracle, BlackLine and HighRadius are still the shortlist. On Xero or QuickBooks Online, the job Rimilia was known for now runs against your own ledger, and there's no longer a reason to be keying it in by hand.
