Single Source Systems' Tax System Interface gives users the ability to calculate AR-side (sales or seller's use) taxes using Independent Systems' Sales Tax System, the Vertex QuantumT Sales and Use Tax system, or Taxware's Tax System.

These solutions report sales tax collected in your SyteLine system, as well as offering monthly tax rate updates for all levels of tax in any U.S. state/possession or any province in Canada. The external tax systems perform all aspects of the tax compliance process including billing, collections and remittance.

Single Source Systems' Tax System Interface works with SyteLine Version 3.5 or higher - and requires the sales tax software and database from either Independent Systems, Vertex or Taxware.
