What our checkout optimization services include
For online stores and B2B sellers, we cover the whole purchase path: checkout, payment and the order handoff to your ERP.
Checkout failure diagnosis
We trace each drop-off to its cause: the total, the form, the payment or the order handoff.
Form and validation fixes
We fix fields and error messages that block buyers, and keep valid entries when something needs correcting.
Payment return handling
We read the real payment status from your provider, so one payment creates exactly one order.
Order handoff to your ERP
We connect checkout to your ERP so each paid order arrives once, and your team sees any failed handoff.
Accurate checkout measurement
We set up abandonment tracking that matches your tools and check real orders before counting a sale as lost.
Handover and support
We hand over the code, configuration and monitoring, and agree who supports your checkout after launch.
Checkout optimization
use cases
Checkout work pays off when buyers want to pay but drop out, fail at payment, or paid orders never reach your operations.
Typical situations where checkout optimization delivers the most value:
-
Many buyers leave at checkout
Shoppers reach checkout but leave before paying, and analytics alone cannot tell you which step stops them.
-
Mobile checkout problems
Buyers on phones struggle with forms, address validation or payment pop-ups that work fine on desktop.
-
Failed or lost payments
Payments are declined, time out, or succeed without an order, and support sorts it out by hand.
-
Surprises in the final total
Buyers drop out when delivery costs, taxes or the final total appear late or differ from what they expected.
-
Orders not reaching operations
Paid orders fail to reach your ERP, warehouse or CRM, so fulfillment and customer service start too late.
-
A new payment or checkout setup
You are adding payment methods, a one-page checkout or B2B checkout rules and want them working before launch.

How we work
Four steps from the first review to a stable release. Each one ends in a result you can check.
1. Map where purchases fail
We review one storefront and its connected systems, then list every drop-off point with its cause.
2. Prioritize the fixes
For each problem we pick the simplest fix that works: a platform setting, a maintained app or a redesign.
3. Build and test the release
We build the agreed changes and test them on guest, signed-in and failed-payment purchases before launch.
4. Monitor after launch
After launch, we check that payments, orders and ERP records still match, and fix any mismatch.

Why companies choose Dinarys
-
01
Delivery governance built into engineering
We bring structure, predictability, and control into software delivery.
Our approach is shaped by PMI-based project management, quality gates, risk management, and a success-first delivery culture.
-
02
Accountable engineering
We do not only take tasks and write code.
We analyze the business and technical context, identify the real bottleneck, challenge weak assumptions when needed, and take responsibility for the technical outcome.
-
03
Senior expertise for CTO-led execution
We support technical leaders with experienced engineers, architecture expertise, and practical roadmap execution.
This helps CTOs and Fractional CTOs stay strategic while having a reliable team to execute.
-
04
Curated teams, not generic outstaffing
Every dedicated team is built around the client’s actual requirements, workflow, culture, risks, and delivery context.
We assess technical skills, soft skills, project fit, culture fit, communication style, and risk factors before proposing engineers.
-
05
Practical AI, from the process
We start from the business process, compare platform features, ordinary automation and AI, and use AI only where it removes real work.
Every AI step gets quality checks and human oversight.
-
06
A partner that has your back
Good delivery depends on trust, honest communication, and people who care about the outcome.
We stay close to the problem, speak openly, involve the right experts, and do not leave clients alone with delivery risk.
Frequently asked questions
We find where purchases fail, then fix forms, payment returns, notifications and the order handoff to your ERP. Every release is tested before launch and monitored after it.
We separate four causes: the buyer rejects the total, the form blocks them, the payment fails, or the order never reaches operations. Each cause needs different evidence and a different fix.
We don’t promise a percentage. We fix verified problems and test the release. To measure the commercial effect, we agree on an A/B test or a fair before-and-after comparison.
We check the payment status with your provider and match it to the store record. The buyer isn’t asked to pay twice, and we test that a repeated notification creates no second order.
Not necessarily. An isolated problem can often be fixed with a platform setting, a maintained app or help from your payment provider. A redesign makes sense when several problems interact.
It depends on the systems involved, the number of problems and how much testing the release needs. We start with one storefront and its connected systems, which keeps the first estimate focused.
