custom apps and saas builds
the software your business actually needs, in production in 12 weeks, in your own repo from the first commit. from usd 18,500.
book a 30-minute scoping call
00 . the short answer
A custom app build starts at USD 18,500 per phase, roughly THB 609,205 at 32.93, fixed price per sprint and never hourly. Sprints run 2 weeks for a productized integration, 6 weeks for a mid-size build like a booking system across four venues, and 12 weeks for fintech-grade production work. Scope and price lock before code starts, so no estimate gets revised at week 9.
A custom app takes 6 to 14 weeks, delivered in phases, or a single sprint of 2, 6 or 12 weeks depending on scope. HorseTonic, a DTC supplement brand, went from WooCommerce to a live Next.js and Supabase storefront in 6 weeks. Every sprint locks scope and timeline in phase 0, before a line of code is written.

01 . what it is
Custom business applications for Bangkok teams, connecting a defined user journey to the systems behind it. Discovery sets the product scope, permissions, data model and acceptance tests before delivery.
bangkok runs on duct tape. line oa for messaging, flowaccount for the books, shopee and lazada and tiktok shop and line shopping pulling in four directions, a shopify or wix shop bolted on the side, and one google sheet holding the whole company together. when a founder finally needs a real product, this city offers three bad doors: a manila body shop that drifts, a thb 80,000 freelancer who vanishes at week five, or a 30-person agency that sells a deck and delivers in nine months. we are the fourth door. senior craft, price on the page, product in production.

sprints are the unit and the scope locks before anyone writes a line. 12 weeks for a series a fintech that needs underwriting v1 live by q4. 6 weeks for an expat f and b group that needs one booking system across four venues. 2 weeks for a thai dtc founder who needs the klaviyo, shopify and line oa seam that no thb 1,000 a month app will ever cover. price fixed at signature. no creep, no surprises, no revised estimate at week 9. agencies protect the estimate. we protect the ship date.
you own everything from the first commit. github repo under your org, supabase project under your billing, vercel team under your account, claude usage on your anthropic console. handover is the default state, not a line item at the end. we are the studio you can fire on a tuesday and still run on wednesday, and no other agency in this city writes that sentence down.
02 . who it is for
illustrative scenario 01
60 employees, a build queue six months past headcount. the board wants kyc v2 for thai business onboarding, a lao expansion module and ai underwriting, all live by q4. her team ships one. we take one of the other two, deliver it in a 12-week sprint, hand the repo back, and her roadmap stops slipping. that is the whole trade.
illustrative scenario 02
thonglor, ekkamai, phrom phong and a catering arm. one booking system across four google calendars, inventory that ties catering to venue stock, and a dashboard he can read on his phone at 6am on a saturday. 6 weeks, fixed price, a real production system instead of a fifth loyverse plugin duct taped to a spreadsheet.
illustrative scenario 03
shopify own-site plus shopee, lazada, tiktok shop and line shopping. she needs the seam where shopify apps give up: marketplace pricing sync, an ai agent answering on line oa, an upsell flow that actually converts. 2-week productized sprints, a number attached to each one. ai is the engine, never the headline.
03 . what you receive
01
technical spec. 12 to 25 pages: user flows, data model, api shape, auth, third-party integrations, observability plan. signed before a single line of code exists.
02
production stack. next.js on vercel, supabase (postgres, auth, storage, edge functions), claude wired into the workflows that deserve it. github repo under your org with ci running on day one.
03
integrations. line oa, line shopping, shopee api, lazada open platform, tiktok shop, shopify storefront and admin api, klaviyo, promptpay, 2c2p, omise, stripe usd, flowaccount and xero asia. we have shipped these already, you are not our lab.
04
auth and access. supabase auth with sso to google workspace, microsoft 365 or line login for thai-facing apps. role based access, audit log, pdpa consent flows written into the schema.
05
observability. sentry for errors, logflare or supabase logs for events, uptime monitoring, and production alerts landing in your slack or line channel during bangkok hours.
06
handover documentation. a 20-page operational manual, deployment runbook and escalation tree. every login under your accounts, every bill in your name, from day one.
07
90-day post-launch care. bug fix sla, two tuning passes, one new integration on request, weekly 30-minute check-ins for a month, then biweekly. we stay on the line after the invoice clears.
04 . timeline

The delivery plan follows discovery. Scope, integrations, access and acceptance tests determine the schedule. A bounded sprint has a written target and dependencies; larger programmes are divided into reviewable phases.
DLVX works from Bangkok with a delivery team and specialist partners. The About page identifies current people and relationships. Published projects explain the scope and credit design or delivery partners, including Heph for the Zalando merchandise platform.
pdpa is in the architecture, not in a policy pdf. purpose of processing stated explicitly, retention set per data category, consent flows documented, a data subject rights endpoint when volume calls for it, supabase rls enforcing access at row level. eu customers on a thai-hosted app get gdpr and eu ai act disclosures wired in alongside. we ship eu-regulated products for a living.
the engagement runs in english. product copy ships in en and th wherever the audience demands it, line oa workflows and thai customer flows included. your thai-fluent reviewers validate copy during phase 2. for expat-led firms, english only is completely fine.
yes, for the right build. boi activity 8 covers software, digital platforms and digital content development, and our phase 0 deliverable tells you exactly where your product stands against it. the filing, thresholds and minimum investment go through your thai boi consultant or in-house counsel. we hand them a spec they can actually submit.

For EU customers on a Thai-hosted app, GDPR and EU AI Act disclosures are wired in alongside, because DLVX ships EU-regulated products every year.
07b . คำถามที่ถามบ่อย
จ้างทำแอปพลิเคชัน custom ในกรุงเทพฯ ราคาเท่าไหร่?
เริ่มที่ USD 18,500 ต่อเฟส หรือราว THB 609,205 ที่อัตรา 32.93 เป็นราคาคงที่ต่อ sprint ไม่คิดรายชั่วโมง แบ่งเป็น sprint 2 สัปดาห์สำหรับงานเชื่อมระบบ, 6 สัปดาห์สำหรับระบบขนาดกลาง เช่น ระบบจองหลายสาขา และ 12 สัปดาห์สำหรับงานระดับ fintech ที่ขึ้น production จริง ล็อกขอบเขตงานและราคาก่อนเริ่มเขียนโค้ด จึงไม่มีการขอปรับราคาเพิ่มตอนสัปดาห์ที่ 9 และทุกราคาประกาศไว้บนหน้าเว็บนี้แล้ว
ทำแอปแบบ custom ใช้เวลานานแค่ไหน?
ใช้เวลา 6 ถึง 14 สัปดาห์ ส่งมอบเป็นเฟส หรือเลือกทำเป็น sprint เดี่ยว 2, 6 หรือ 12 สัปดาห์ ตามขอบเขตงาน ตัวอย่างจริงคือ HorseTonic แบรนด์อาหารเสริม DTC ที่ย้ายจาก WooCommerce มาเป็นหน้าร้าน Next.js กับ Supabase ใช้เวลา 6 สัปดาห์จนขึ้นใช้งานจริง ทุก sprint ล็อกขอบเขตและกำหนดเวลาไว้ตั้งแต่เฟส 0 ก่อนเขียนโค้ดบรรทัดแรก
ทีมอยู่ที่กรุงเทพฯ จริงไหม หรือส่งงานไปทำต่างประเทศ?
DLVX วางแผนและพัฒนางานตามขอบเขตที่ตกลงร่วมกัน ตรวจสอบระบบและข้อมูลก่อนเริ่มงาน พร้อมกำหนดผู้รับผิดชอบ วิธีทดสอบ และการส่งมอบ ผลงานแต่ละโครงการมีขอบเขตแตกต่างกัน โปรดดูรายละเอียดในหน้าผลงาน
ส่งมอบงานแล้วได้อะไรบ้าง?
ได้โค้ด production ใน GitHub ของคุณตั้งแต่ commit แรก, Supabase project และ Vercel team ที่ผูกกับบัญชีและบิลของคุณเอง, เอกสาร technical spec 12 ถึง 25 หน้า และคู่มือ handover 20 หน้าพร้อม runbook สำหรับ deploy จากนั้นดูแลต่ออีก 90 วันหลังเปิดใช้งาน มี SLA แก้บั๊ก ปรับจูนระบบสองรอบ และเพิ่ม integration ใหม่ได้อีกหนึ่งรายการ ทุกอย่างเป็นของคุณ เลิกจ้างวันอังคาร ระบบก็ยังเดินต่อวันพุธ
ระบบที่ทำรองรับ PDPA ด้วยไหม?
รองรับตั้งแต่ตอนออกแบบสถาปัตยกรรม ไม่ใช่มาตามแก้ทีหลัง ระบุวัตถุประสงค์การเก็บข้อมูลชัดเจนในนโยบายความเป็นส่วนตัว ตั้งระยะเวลาเก็บข้อมูลแยกตามประเภท ทำ consent flow เป็นเอกสาร และใช้ RLS policy ของ Supabase คุมสิทธิ์ระดับแถวข้อมูล ถ้ามีลูกค้าในยุโรปด้วย เราทำเรื่อง GDPR และ EU AI Act ควบคู่ไปกับ PDPA เพราะเราส่งงานที่อยู่ใต้กฎหมายยุโรปเป็นปกติอยู่แล้ว
จ้างฟรีแลนซ์ทำแอป กับจ้าง agency ต่างกันยังไง?
ต่างกันที่ใครยังอยู่กับงานถึงสัปดาห์ที่ 9 ฟรีแลนซ์ราคา THB 80,000 ถูกจริงแต่หายกลางทางบ่อย ส่วน agency 30 คนก็ช้า เน้นทำ deck มากกว่าส่งของ และแพงกว่า DLVX อยู่ตรงกลางที่ไม่มีใครยืน ทีมซีเนียร์ล้วน ไม่มีเด็กฝึกงาน ไม่มีการส่งต่องาน ราคาคงที่ต่อ sprint ประกาศบนหน้าเว็บ โค้ดเป็นของคุณตั้งแต่วันแรก ส่งงานมาแล้ว 60 กว่าแพลตฟอร์มตั้งแต่ปี 2021 มีเคสจริงอย่าง HorseTonic, Enky และ Jobfin ให้ดู
