Feedback from clients across Thailand

PK

Prasert Klaewkla

Operations Manager · Korat, TH

"We started with an Anchor Review because we were not sure where AI would actually help us. The report was written in plain language and gave us three practical options with realistic estimates. We chose to proceed with one — and the integration has been running without interruption for about four months."

Suchada Rattana

Director · Nakhon Ratchasima, TH

"The pricing was clear before we started, which made the decision much easier to get internal approval for. Somchai is our named contact and he knows our system well. The quarterly review last month was useful — we covered a few upcoming API changes and he had a plan for each one."

Anuchit Wongkham

IT Lead · Khon Kaen, TH

"We have tried to set up API integrations ourselves before, and things inevitably drift after a few months. What Wichai Systems delivered was documented properly and they flagged a breaking change from OpenAI before it affected us. That alone justified the Hold-Fast cost for the year."

Narinee Chaiyaporn

Owner · Udon Thani, TH

"I was hesitant to bring in an external team for something as sensitive as system integrations. The data processing agreement they sent before starting gave me enough confidence to proceed. The review itself was thorough — they found one connection we had not considered and it turned out to be the most practical option."

Thanachai Laophan

Systems Manager · Nakhon Ratchasima, TH

"The handover session at the end of the Fixed Integration was genuinely helpful. Nattaya walked through the architecture notes with us and made sure our own team understood how the pieces fit together. Most vendors would have just handed over a ZIP file. This was a different experience."

Bunyong Phatcharawit

Finance Director · Buriram, TH

"The fixed price in Baht was important for our budgeting process. We knew what we were committing to before any work began, and that made internal approval straightforward. The Anchor Review came in exactly as scoped. We are now planning the Fixed Integration."

Case Studies

Detailed client journeys

Manufacturing · Nakhon Ratchasima

Connecting a document processing AI to an ERP system

Challenge

A mid-sized manufacturer was manually re-entering supplier invoices from PDF format into their ERP. The process was time-consuming and introduced transcription errors. They wanted to explore whether AI could extract and route the data automatically, but had no internal engineering capacity to assess the options.

Solution

An Anchor Review identified two viable options. They chose a fixed integration connecting a document AI API to their ERP's import endpoint. The build took four and a half weeks and included a validation layer that flags low-confidence extractions for manual review rather than processing them automatically.

Outcome

The integration processes around 80% of invoices without staff involvement. Transcription error rate dropped substantially. The client enrolled in Hold-Fast after the build to keep the connection maintained as their ERP version updates over time.

Logistics · Khon Kaen

Routing customer queries through an AI triage layer

Challenge

A logistics company received a high volume of inbound customer enquiries across email and a web form. Most enquiries were routine — delivery status, rate requests, area coverage. Staff were spending the majority of their time on repetitive responses rather than handling complex or sensitive cases.

Solution

The Anchor Review identified a triage layer — an AI-assisted classification and response system — as the appropriate integration point. The Fixed Integration built this connection between their email platform and a language model API, with the system drafting responses to routine enquiries and routing complex cases directly to staff.

Outcome

Within the first two months, around 65% of inbound enquiries were being handled by the triage layer without staff intervention. Complex cases continued to reach the team flagged and pre-summarised. Response time on routine enquiries improved significantly.
