# Accounts Payable: Manage Supplier Invoices and Payments
> Capture supplier invoices automatically, manage approval workflows, schedule payments, and track aging — one AP inbox across every entity and currency.
Every supplier invoice your company receives — facturas, boletas, expense reports, and vendor bills — needs to be captured, approved, and paid on time, without slipping through the cracks. Sintropix centralizes all of that into a single AP inbox that pulls from your connected integrations and accepts manual uploads, so your team always has a clear picture of what is owed, to whom, and when.
## AP Inbox
Supplier invoices arrive in the **AP Inbox** from two sources: automatically from connected integrations (banks, expense platforms, and procurement tools) or uploaded manually by your team. Each invoice in the inbox has a clearly visible status so you can see where it is in the workflow at a glance:
| Status | Meaning |
| ------------- | -------------------------------------------------------------------- |
| **Draft** | Received and parsed, awaiting finance team review |
| **Approved** | Reviewed and approved; ready to be scheduled for payment |
| **Scheduled** | Payment date set; the journal entry is staged for posting |
| **Paid** | Payment has been made and the entry has posted to the general ledger |
You can filter the inbox by entity, supplier, due date, currency, and status. Sort by due date to quickly identify what needs attention today.
## Invoice Workflow
Invoices enter Sintropix either automatically from a connected integration (Rinde Gastos, Ramp, Xpendit, or a bank feed) or by manual upload (PDF, XML, or image). If your bank feed is connected, payment confirmations from Santander, BCI, BBVA, or any other integrated bank also flow in automatically.
Sintropix extracts the **supplier name**, **total amount**, **currency**, **due date**, **line items**, and **tax breakdown** from the invoice document. The extraction is visible in the invoice detail view, and your team can correct any field before approving.
The invoice moves to **Draft** status in the inbox. A finance team member opens it, confirms the extracted fields, and clicks **Approve**. If the invoice amount differs materially from a linked purchase order, **Erwin** flags it for review automatically with a note explaining the discrepancy — so mismatches don't slip through unnoticed.
After approval, set the payment date and payment method. Sintropix stages the journal entry — debit the relevant expense or asset account, credit Accounts Payable — and posts it to the general ledger on the payment date. Once payment is confirmed, the AP balance clears and the invoice moves to **Paid**.
## Aging Report
The **AP Aging Report** gives you a complete picture of outstanding obligations grouped by how overdue they are:
| Bucket | What it shows |
| ---------------- | -------------------------------------------------------------------------------------- |
| **0 – 30 days** | Invoices due within the next 30 days or not yet past due |
| **31 – 60 days** | Invoices 31 to 60 days past their due date |
| **61 – 90 days** | Invoices 61 to 90 days past due — worth prioritizing to protect supplier relationships |
| **90+ days** | Significantly overdue invoices that require immediate attention |
Filter the aging report by **entity** to see each subsidiary's AP position separately, or run it consolidated across all entities. Filter by **supplier** to pull up everything owed to a single vendor.
Invoices in the 61–90 and 90+ buckets may trigger late payment penalties or strain supplier relationships. Review the aging report weekly and use the **Scheduled** status to show suppliers that payment is on the way.
## Multi-Currency AP
Your subsidiaries receive invoices in local currencies — Chilean pesos, Mexican pesos, Colombian pesos, Brazilian reais, Peruvian soles, and Argentine pesos — as well as in USD and EUR. Sintropix handles all of them.
When an invoice is captured, Sintropix records the **transaction currency** (the currency on the invoice) and automatically converts it to the entity's **functional currency** using the exchange rate in effect on the invoice date. If your reporting currency is USD, a second conversion layer produces the USD equivalent for consolidated reporting.
FX rates are updated daily. If the exchange rate between the invoice date and the payment date produces a gain or loss, Sintropix posts the **FX difference entry** to your foreign exchange gain/loss account automatically — no manual calculation required.
Connect your expense management platforms — **Rinde Gastos**, **Ramp**, or **Xpendit** — so that employee expense reports flow into the same AP inbox alongside supplier invoices. That way your entire payables picture, employee and vendor, is in one place with the same approval workflow and aging view.
Track what customers owe you with the same clarity you have on what you owe suppliers.
Connect Buk, Rankmi, Rinde Gastos, Ramp, and Xpendit to automate expense capture.
