What accounts receivable automation is
Accounts receivable automation is the pipeline that issues invoices and tax invoices, runs the collections cadence on due dates, reconciles gateway and bank to open items and feeds aging and delinquency. With Abstra, the cadence and reconciliation are customized per customer: templates, groups, gateways and write-off rules follow your operation.
Proof in accounts receivable
Less manual collections. More cash on time.
Automated collections and invoice management
In the BeFly Holding case, collections and invoice management were automated: centralized open items and business groups, collection email send/resend with tracking, SQL Server/MySQL sync and dashboards with aging and credit risk.
Daily receipts reconciliation
In the Clinicorp case, daily receipts reconciliation matches statements, payments and invoices, with receivable and fee write-offs in the ERP and reports for financial follow-up.
If your accounts receivable looks like this, we fix it.
“Every month someone spends hours sending collection notices invoice by invoice, by hand.”
“I reconcile the statement against the ERP's open items by hand. It causes errors and delays the write-off.”
“Each gateway has a different report; matching it to the receivable is spreadsheet hell.”
“We don't have real-time aging or delinquency: the report is always out of date.”
Cadence and receivables
A customized collections cadence and receivables reconciliation in one pipeline.
Every portfolio has different due dates, channels and gateways. We build the cadence and receivables match the way your team already collects and writes off in the ERP.
Cadence by group, channel and due date
Email, WhatsApp and bill on the D+X your operation uses, with templates and a send trail. Exceptions become human review without stalling the queue.
See processGateway/bank × open-item reconciliation
Payouts and statements matched to open items, dedup and idempotent ERP write-off. Only discrepancies stay in the queue.
See processBilling and tax invoices at scale
Issuance from the ERP/CRM, cancellation and SEFAZ lookup in the flow, before collections go out.
See process100% shaped per customer
Business groups, multi-ERP, aging and delinquency escalation follow your house rules, not a generic template.
Where to automate first
How automated collections cadence and reconciliation work
Invoicing, collections cadence, reconciliation, delinquency, credit and reports. Start with the process that hurts most today.
Billing and invoice issuance
Generates invoices and issues tax invoices at scale from the ERP/CRM, with cancellation and lookup.
See processCollections management
Due-date cadence by email and WhatsApp, with templates and groups.
See processPayment reconciliation
Matches gateway/bank to open items and writes off with dedup.
See processDelinquency management
Real-time aging, portfolio prioritization and risk escalation.
See processCredit analysis
Score and rules at receivable intake, with a trail for sales/finance.
See processReceivables reports
Portfolio, status and performance view without consolidating spreadsheets by hand.
See processAbstra vs ERP cadence, billing SaaS and spreadsheet + RPA
What changes when the pipeline must write off open items in the ERP and truly reconcile gateways.
| Criterion | Abstra | Native ERP cadence | Billing/collections SaaS | Spreadsheet + RPA |
|---|---|---|---|---|
| Customized cadence | Groups, D+X, WhatsApp and templates per portfolio | Limited to AR module fields | Strong on sends, weak on ERP rules | Macros and manual reminders |
| Receivables reconciliation | Gateway/bank × open item with idempotent write-off | Depends on ERP integration | Payout report, manual ERP write-off | Fragile mapping spreadsheet |
| Multi-ERP / multi-gateway | One pipeline, many sources and ERPs | One ERP per instance | Gateways the vendor supports | Script per portal |
| Aging and delinquency | Fed from reconciled status | AR module report | SaaS dashboard, not the ERP | Weekly manual consolidation |
| Best for | AR with house cadence, gateway and ERP write-off | Simple operation inside one ERP | Collection sends without deep reconciliation | Low volume, few gateways |

Beyond named cases
Real accounts receivable patterns
Financial services provider
An email collection platform triggered by due date, with templates and groups: ~80% less manual sending time.
Multi-entity group
Reconciliation, accounts receivable and email/WhatsApp collections spanning multiple ERPs and banks.
Ticketing OTA
Issues service invoices for fees at scale, with cancellation and lookup flows.
B2B SaaS / fintech
Syncs receivables between ERPs, creates invoices and matches gateways (Pagar.me/Stripe) to open items.
Accounts receivable needs open-item write-off, a valid tax invoice with SEFAZ and a cadence that runs on its own on schedule. Email sends alone do not reconcile the gateway or update aging.
Why not generic AI?Frequently asked questions
Can we customize the collections cadence by portfolio?+
Yes. Business groups, D+X, channels (email/WhatsApp/bill) and templates follow your operation’s rules. The pipeline is built per customer; exceptions go to human review with an audit trail.
Which ERPs and gateways do you integrate?+
Omie, NetSuite, Protheus, SAP, Conta Azul, Granatum and others via API; Pagar.me, Stripe, PagSeguro, Vindi and bill/PIX/payment files. With no API, we use a browser agent or report ingestion.
Does the collections cadence run on its own?+
Yes. Triggers by due date and rule (email/WhatsApp/bill), with templates and an audit trail. Exceptions go to human review.
Does it reconcile gateway and bank with the ERP?+
Yes. We match payouts/statements to open items, write off with idempotency and leave only discrepancies in the queue.
Can we see aging in real time?+
Yes. The pipeline feeds aging and delinquency from reconciled statuses, without a late weekly report.
Do you replace my accounts receivable ERP?+
No. Abstra acts as the pipeline that collects, reconciles and writes off in the ERP you already use. Issuance and open items stay in your system of record.
Where should we start?+
With the collections cadence, invoice issuance at scale or payment reconciliation. Use the processes below.
