Questions and answers

An extension adds a feature to your Microsoft Dynamics 365 Business Central without changing the standard product. It can add a field, a rule, an approval step, a report or a link to another system.

Because it sits beside the standard product, it can be added, updated and removed on its own.

No. You describe what you need in plain words in a short wizard. We fill in the technical details, and you review the result as a storyboard with screens, not as code.

You receive a functional document that describes your extension in plain language.

It depends on the size of the extension and on how many review rounds you need. A small change takes less time than a large one, and quick answers from you shorten every stage.

You see the current stage in your account at all times.

Business Dynamics Pro keeps the intellectual property. You receive a licence to use the extension in the environments you name.

You receive the functional document that describes your extension in plain language. If you want the source code, you can buy it for an app after it is delivered, under a separate licence.

We install it for you automatically: first in your sandbox, a safe copy of your system, where you test it, then in production when you are happy.

This managed install is how every app is delivered. You do not handle any files.

Business Central updates twice a year. A support plan checks your extension against each update and fixes it if an update breaks what you approved. Without a plan, you can still request fixes as priced changes.

Support plans cost a share of your app's build price each month: Essential (1.25 % of the build price a month, at least USD 49), Standard (1.75 % of the build price a month, at least USD 99) and Priority (2.5 % of the build price a month, at least USD 249).

We do not need your production data. We design and test using the CRONUS sample company that comes with Business Central, never your live records.

All instructions and screenshots in your manual use the CRONUS sample company, never your records.

We store what you send us: your request, any files you attach and the designs we create. Please do not paste passwords or personal data into a request. Which companies process this information and how long we keep it are listed on our privacy page.

We build extensions that add to or change how your system works. We do not change the standard product itself, and we do not build things that bypass its security or licensing.

Some requests are very large or need a closer look. For those we prepare a custom quote, or tell you honestly that another route is better.

Yes. If you are a Business Central partner, you can request extensions for your clients. Our partner program: Referral partners earn a commission (10 %) on a client's first build; Reseller, Premier and Elite partners take 20 %, 30 % and 35 % off build prices.

White-label delivery, with your name in place of ours, is available at the higher levels. Business Dynamics Pro keeps the intellectual property at every level, and the partner sublicenses to its client. Discounts apply to builds and changes, not to subscriptions or source code.

Every extension comes with a training manual. It covers what the extension does, how to check the install, how to set it up, who needs which permissions, every daily task as a numbered walk-through with screen previews, and every page and action.

It also covers notifications and approvals, reports, troubleshooting, common questions, a glossary and the version history.

It is a single page you can open without an internet connection, and you can also read it in your account.

You pay for each build in two equal parts. You pay 50 % when you accept the quote, and the build starts. You pay the other 50 % when the extension is built and tested, before we install it.

Designing the extension with you comes first and is part of your subscription. The subscription starts with a 14-day trial, so you can see a design and its functional document before you commit.

Your price depends on how complex your extension is and how many parts we need to design: screens, records, reports, approvals and links to other systems. Simple extensions usually cost USD 2,000 to 5,000, standard ones USD 5,000 to 12,000 and advanced ones USD 12,000 to 20,000. Above USD 20,000, we prepare a custom quote after reviewing the design.

You see the breakdown before you accept.

We recommend a dedicated sandbox with the CRONUS sample company. We install there first so you can test safely, and move to production only after you accept it. We do not need your live data to design or test.

For installation we ask an administrator of your Microsoft environment to give us permission to install extensions on your behalf. This is called delegated admin consent. You stay in control and you decide which environments we may use.

Yes. A change after approval is treated as a change request. We design it with you and price only the difference.

We build from the design you approve. For 30 days after installation we fix anything that does not match it. Our total responsibility never exceeds what you paid for that extension.

Tell us if something is wrong. You test in your sandbox before production, which is the best moment to find problems. After the warranty, you can always request changes, priced on the size of the change.

A monthly subscription gives you access to design your apps with us, to receive the functional document for each app, and to come back to your released apps and ask for changes, which cost less than starting again. Plans start from USD 49 a month, with a 14-day trial.

The cost of building an app is separate. It is calculated from the size of the approved design and paid in two parts for each build.

If your subscription lapses, the apps you already have keep running. Design and change requests pause until it resumes.

Yes. Open the app in your account, request a change and describe it in plain words. We start from the released version, show you a storyboard of the change and price only the difference.

The new version is installed as an upgrade, in your sandbox first.

We install it for you. This is the standard way, and it is automatic: first in your sandbox and then in production, with the permission you give us.

Downloading the app package is available only to customers who have purchased the source code for that app. You accept the licence terms before you download.
