How it works

Built to stay out of your way.

Your workflow in Cetec doesn't change. Nexline runs as a monitored background service on AWS, watching Cetec for new invoices, customer changes and product changes, and processing each at a speed matched to how urgent it actually is.

Smart background processing

Real-time sounds better than it works.

A tax call on every keystroke adds 3–5 seconds to every invoice: minutes of standing around on a busy afternoon. Nexline batches work by priority instead.

Immediately
Posted invoice

Your compliance-critical moment. Calculation and the Avalara commit happen on post.

5–10 min
New invoice

Room to edit the order before tax locks in, with accurate tax before anything ships.

15 min
Customer or exemption update

New accounts and certificate changes are live well before that customer's first invoice.

30 min
Product & tax-code change

Catalog updates affect future invoices, so they ride in the background.

Exemption certificates

From request to applied exemption, in five steps.

  1. Request

    An exempt or newly onboarded customer is flagged in Cetec, and Avalara issues a CertExpress request.

  2. Customer completes

    The customer fills out a guided, state-specific wizard: the correct form, the first time.

  3. Validate

    Avalara checks the certificate against that state's requirements and stores the signed document.

  4. File to Cetec

    Nexline writes the validated certificate and exemption data onto the Cetec customer record.

  5. Apply

    The next invoice for that customer calculates with the exemption and entity use code applied.

The certificates module requires an Avalara subscription that includes exemption certificate management. We confirm entitlement with Avalara before install.

Your dashboard

A two-minute daily habit.

Most customers spend under five minutes a day on Nexline. Many check once a week. If something needs attention, the system tells you.

Getting live

Guided setup. Nothing to install.

You get a secure link to your Nexline dashboard and work through five steps in the browser, with us on the call. Most customers finish in a single session.

  1. Open the dashboard

    A secure link arrives by email. No software on your machines.

  2. Connect Avalara

    Account ID, license key, company code and environment, then Test Connection.

  3. Connect Cetec

    Your Cetec subdomain and JSON API token, verified the same way.

  4. Optional bulk sync

    Pre-load existing customers, certificates and product tax codes.

  5. Go live

    Review the summary, complete setup, start invoicing.

From Avalara

  • Account ID (Account Settings)
  • License key, issued at signup
  • Company code, usually DEFAULT

From Cetec & your records

  • Cetec subdomain (company.cetecerp.com)
  • JSON API token (Admin › Config Settings)
  • Primary shipping address, for nexus

Setup can be paused and resumed at any point, and services can be disconnected and reconnected without risk to your Cetec or Avalara data.
