Sales & Use Tax System Design That Gets Compliance Right at the Source

We design and configure your end-to-end sales and use tax system — tax engine, ERP and e-commerce integration, and clean processes — so compliance runs correctly from day one.

Most sales tax problems are not filing problems — they are setup problems. When the tax engine is misconfigured, product taxability is wrong, or the ERP and cart are not talking to each other, errors get baked into every transaction and only surface during an audit. Fixing it after the fact is expensive. Designing it correctly from the start is not.

We design and configure your end-to-end sales and use tax system: the tax calculation engine, the connection to your ERP, billing, and e-commerce platforms, product taxability mapping, exemption certificate handling, and the reporting that feeds clean returns. The result is a system where the right tax is charged on the right transaction automatically — and where your data is already audit-ready.

Scope

What system design includes

  • Tax engine selection & configuration — the right platform for your stack, configured to your product catalog and nexus footprint.
  • Integration — connecting your ERP, billing, and e-commerce/marketplace systems so tax data flows without manual re-entry.
  • Product & service taxability mapping — so SaaS, digital goods, shipping, and bundles are taxed correctly per state.
  • Exemption certificate workflow — collection, validation, and storage so exempt sales survive an audit.
  • Reporting design — clean, reconcilable data that makes every return fast and defensible.
Timing

Best time to do this

Ideal moments: launching in new states, migrating ERPs or carts, hitting economic nexus in multiple states, or cleaning up after a messy audit. If your current setup produces numbers you do not fully trust, that is the signal.

FAQ

System design & automation — FAQ

What is sales and use tax system design?

The configuration of your tax engine, integrations, and processes so sales and use tax is calculated, collected, and reported correctly and automatically across your systems.

Do you work with our existing software?

Yes — we work with major tax engines, ERPs, and e-commerce platforms, and we recommend a change only when the current stack genuinely cannot support your compliance needs.

Quick FAQs

Here are some answers to Frequently Asked Questions.

What is the filing deadline?

Each jurisdiction has different deadlines. Some returns are due monthly, quarterly, semi-annualy, or annually. 

Can I get an extension?

Some states do offer extensions for returns, but not all. Depending on your situation you may qualify for an installment plan. 

What if I don't know where I need to file?

We can help you figure it out. Send us a message or give us a call to get started.

I received a delinquency notice from a state. What should I do?

Depending on the notice, you may need to file back returns with that state. We offer notice handling services, contact us to get started. 

What if I don't want to eFile my returns?

Most states require electronic filing now. It is the most convenient and fastest way to file. 

Can I file my return myself?

Our services are offered individually so you may choose to have us complete a nexus determination and register accounts, but not file returns. That is ultimately up to you. We understand each business has different resources and business needs. We’ll work with you to create a custom plan to meet those needs. 

What do I need to get started?

To get started you will need to send us a message detailing your business needs. After that, your tax preparer will walk you through the next steps.

Can I setup a meeting with my tax preparer?

Absolutely! Meetings are included with our services. We can do video meetings or phone calls, whichever is most convenient to you.
