Sage ERP integration with one source of truth
Sage 100 runs accounting, inventory, sales and reporting for thousands of small and mid-sized firms in manufacturing, distribution, wholesale and retail. It rarely works alone. We link it to your web store, CRM, payroll, carriers and tax engine so data is keyed once and every integrated system reads the same records.

Store orders, products and refunds both ways
Orders, inventory, customers, products, payments and refunds pass between Sage 100 and Shopify, BigCommerce, Magento or Adobe Commerce. A customer added in your CRM appears in the Sage database within minutes.

Carriers, card payments and sales tax
ShipStation, FedEx and UPS connectors send orders to the carrier and return labels and tracking numbers to Sage, adjusting stock as they go. Stripe, Authorize.Net and Sage Payment Solutions cover cards, ACH, refunds and recurring billing. Avalara or Vertex works out multi-jurisdiction sales tax and books the liability.

CRM and payroll posting to the same ledger
Salesforce, HubSpot or Microsoft Dynamics receive customer records, opportunities, quotes and invoicing history, so reps can see open receivables. Payroll from ADP, Paychex or Gusto comes back into the Sage ledger for job costing and compliance.

Built for your Sage 100 version and custom fields
The Sage 100 API changes between releases, so we test against the version you run and again after each upgrade. Work starts in a sandbox that mirrors production, leaves your custom modifications untouched, and batches or queues traffic to stay inside Sage 100 throughput limits.

Questions
Which systems can connect to Sage 100?
Online stores such as Shopify, BigCommerce, Magento and Adobe Commerce; CRMs such as Salesforce, HubSpot and Microsoft Dynamics; payroll providers; FedEx, UPS and ShipStation; payment processors; and the Avalara and Vertex tax engines.
Do you use a ready-made connector or a custom build?
Whichever the job needs. Native connectors cover simple cases, middleware solutions such as Clarity Connect handle routing, transformation, error retries and monitoring, and custom builds on the Sage 100 API cover deeper requirements.
How long does a project take?
A single pre-built connector usually ships in 4-8 weeks. Work spanning eCommerce, CRM and payroll takes 2-5 months, and a full enterprise rollout 4-9 months, depending on the systems, data volume and custom configuration.
Is the connection secure?
Yes, when it is built with encrypted connections, role-based access, audit logging and managed secrets for API keys.
