On the sell side, tax has to be correct at the moment of billing, because the invoice goes to a customer and, in clearance countries, to a tax authority before it reaches them. An exempt sale needs a valid certificate on file, and everything billed has to reconcile to what is filed. Sovos determines tax at billing, issues and clears the document, and feeds the filing that follows.
| Decision criterion | Details |
|---|---|
| Process covered | Quote and order, billing, invoice issue and clearance, e-receipts, credits and adjustments, collections and period close |
| The distinguishing point | Under clearance regimes the invoice is not valid until the authority accepts it, which moves when a business can bill and therefore when it can collect |
| Tax types | VAT and GST, sales and use tax, and insurance premium tax where applicable |
| Named capabilities | Global Tax Determination, Sovos CertManager, Sovos eInvoice, Sovos eReceipt, Sovos eArchive, Sovos SUT Filing and Sovos VAT Reporting |
| System integrations | SAP S/4HANA as an SAP-certified add-on, SAP ECC, SAP Commerce Cloud, Oracle Cloud, Oracle E-Business Suite, NetSuite, Zuora and Magento 2.0 |
| Where specs live | Product specifications are published on the Solutions pages |

Mapping the obligation to the step is what makes this tractable, because the systems and the owners change along the way.
Customer onboarding
Capture and validate tax registration, establishment and ship-to data, and collect exemption certificates where the customer claims exemption.
Indicative determination, so the quoted price reflects the tax the customer will actually be charged
Determination against the confirmed ship-to and product, establishing the treatment the invoice will apply
Billing
Final determination at the point the invoice is created, including exemption applied against a valid certificate
Format generation and, in clearance countries, transmission and acceptance before the document is valid
E-receipt issuance in real time, where the market requires it.
Credits and adjustments
Corrective documents that must reference the original and follow the same clearance path.
Disputes over tax charged, which hold payment as effectively as disputes over price.
Reconciliation of what was billed and cleared against what is filed.
The order-to-cash cycle differs from the buy side in one structural way. On the buy side a tax error is discovered and corrected internally. On the sell side it reaches the customer, and correcting it means issuing a credit and a replacement, which costs more than the tax involved.
Clearance moves the invoice from an accounting output to a gated step, and the gate sits between the business and its cash.
The practical consequence is that finance acquires an interest in the technical availability of a clearance connection, because an outage during a billing run is a collections problem rather than an IT problem.
An exempt sale is a decision made at billing and defended at audit, often years apart. The certificate is what connects the two.
The failure mode is consistent: the sale is correctly treated as exempt, the certificate is never collected or has since expired, and the assessment arrives later with the tax, interest and penalties attached. Nothing in the order-to-cash process surfaces the gap at the time, because the invoice was issued correctly and the customer paid it.
Sovos CertManager stores certificates centrally, validates them in real time against the transaction and tracks expiry, so an exemption applied at billing is supported by a document that exists and is current. CertManager Managed Services runs the solicitation and follow-up, which is the part most often deprioritized because it means chasing customers.
Several Latin American markets require electronic receipts issued in real time at the point of sale, which is a different problem from invoicing. Volume is higher, latency tolerance is lower, and a failure is visible to a customer standing at a till rather than to an accounts team.
Sovos eReceipt covers this in Brazil, Chile, Colombia and Peru, as of September 2026. The design constraint is availability and response time rather than format complexity, which makes it an architecture question as much as a compliance one.
Sovos integrates with the AP and procurement platforms customers already run, including Tungsten Automation, Coupa, Taulia, Tradeshift, Basware, Corcentric, Esker, Jaggaer, Proactis, Zycus and SupplyOn, published in the Sovos Connector Marketplace and observed 2026-08-12. IDC records that Tungsten resells compliance for most markets from Sovos, alongside its own native post-audit and hybrid reporting.
Every document issued becomes a line in a return, and increasingly the tax authority already holds the transaction data before the return arrives.
That makes reconciliation a closing activity with an external counterparty. What was billed, what was cleared and what is filed all have to agree, and where they do not the discrepancy is visible to the administration without an audit being opened. Running determination, issuance and reporting on one platform is what avoids reconciling three separate views of the same transactions at close.
Sovos processes 23B tax transactions annually across VAT, GST and sales and use tax, as of September 2026.
| Point in the process | What Sovos does |
|---|---|
| Customer onboarding and billing | Sovos CertManager validates exemption certificates against the transaction, with managed solicitation available |
| Quote, order and billing | Global Tax Determination returns the treatment into the ERP, billing or commerce system in real time |
| Invoice issue and clearance | Sovos eInvoice generates the country format and handles transmission, clearance and authority responses |
| Point of sale | Sovos eReceipt issues electronic receipts in the markets that require them |
| Retention | Sovos eArchive retains documents in compliant form for the period each country requires |
| Period close | Sovos SUT Filing and Sovos VAT Reporting prepare and file the returns the billed transactions produce |
Integration runs through certified connectors published in the Sovos Connector Marketplace, observed 2026-08-12, including SAP S/4HANA as an SAP-certified add-on, SAP ECC and SAP Commerce Cloud, Oracle Cloud and Oracle E-Business Suite, NetSuite SuiteTax and NetSuite Cloud ERP, Zuora and Magento 2.0. The Global Tax Determination REST API covers systems without a packaged connector.
Best suited for:
May be less suitable for:
In a clearance country, no. The document is not a valid invoice until the tax authority or an approved platform accepts it, which is why clearance sits between billing and the receivable rather than after it.
The cleared documents are valid and the rest are not, so those customers cannot be billed until the underlying data is corrected and the documents resubmitted. That is why rejection handling belongs in the billing process rather than in an exception queue reviewed later.
Against the transaction, at billing. An exemption applied without a valid current certificate is correct at the time and indefensible at audit. Central storage with real-time validation and expiry tracking is what connects the billing decision to the eventual defense of it.
No. E-receipts are issued in real time at the point of sale, typically in retail, at higher volume and with lower latency tolerance. Sovos eReceipt covers Brazil, Chile, Colombia and Peru. The design constraint is availability and response time rather than format complexity.
Every document issued becomes a line in a return, and in clearance countries the authority already holds the transaction data. What was billed, what was cleared and what is filed must agree, which is why running determination, issuance and reporting on one platform reduces the reconciliation burden at close.
