Say you're running a small POS counter in Manila that just started taking WeChat Pay from tourists. Or you're a Hanoi retailer eyeing a working-capital loan through the same software you already use to ring up sales. Three vendors moved this week: DOKU, KiotViet, and HitPay. None of them sent an email about it. You just notice a new field on the product page, or a different button on the home screen.
Most of these changes look small in isolation. A dropdown field here, a loan menu there. But line them up across a month and a pattern shows up. SEA SaaS vendors are turning existing merchant data into the next product they sell you, whether that data is a product catalog or a year of POS transactions.
DOKU
On June 26, 2026, Digital Catalog gained Custom Fields per Product. Merchants can configure up to three fields per product, either a text input or a dropdown, shown to shoppers before checkout, and mark each one Required or Optional. Products still move through Draft, Published, or Unpublished before edits go live, with a verification step in between.

DOKU doesn't charge a setup fee or a monthly fee on its payment gateway; merchants pay per successful transaction. QR sits around 0.7%. Digital wallets range from 1.5% for DOKU's own e-wallet and Dana up to 2%-4% for ShopeePay. Minimarket cash payments run Rp2,500 at Alfamart up to Rp6,500 at Indomaret. That fee structure is exactly why the custom-field feature matters more than it looks. A merchant selling made-to-order goods can now capture size or engraving details at checkout, instead of chasing the same details over WhatsApp an hour later. Small change, real time saved, and it costs the merchant nothing extra to turn on.
KiotViet
On June 26, 2026, KiotViet launched embedded lending with VietCredit through a new in-app "Vay vốn" (Get Financing) menu, offering "Tin Vay Biz" loan packages. The flow: pick Vay vốn from the home screen, choose a package, submit and e-sign the contract in-app, then get an underwriting decision and funds sent to a bank account. Merchants need a national ID, business license, and a purchase invoice. KiotViet says there are no hidden fees and no insurance fees attached.

KiotViet's own software runs 250,000₫ a month (about USD 9.60) on the Support tier, 310,000₫ (roughly USD 12) on Professional, and 490,000₫ (close to USD 19) on Premium, prices that haven't moved in this window. Folding a loan product into that same dashboard is the smarter move here. The software already sees a shop's daily cash flow, so underwriting can lean on real sales history instead of the bank statements a lender would normally spend weeks requesting. A phở stall owner in Da Nang who got turned down at a bank branch last year might actually clear this bar, simply because the receipts already live inside KiotViet.
HitPay
HitPay added WeChat Pay acceptance for Philippine merchants on June 25, settling directly in PHP across Online Store, POS, and Borderless QR channels. On June 17, an in-dashboard AI Assistant arrived that answers plain-language questions about sales figures, payment-method status, and account verification. On June 8, LINE Pay support landed for THB payments across Online, In-Person, Borderless QR, and Recurring Billing. On June 5, HitPay added embedded alternative-payment-method flows with direct links inside merchant apps, plus wallet top-up for Malaysia and Philippines merchants. On May 26, a Bukku accounting integration arrived to auto-sync sales, payments, and refunds, and ShopBack Pay in-store QR acceptance went live for Singapore merchants at physical counters.

HitPay charges no monthly fee on its standard plan. Online domestic card payments run 2.8% plus S$0.50 per transaction, in-person domestic cards drop to 2.5% with a S$0.20 minimum, and PayNow costs just 0.4%. Foreign cards add roughly another percentage point on top of the domestic rate. Five feature launches in five weeks is a fast clip for a payments company with no subscription revenue sitting under it. That pace tells you HitPay is betting on transaction volume across as many SEA wallets as it can plug in, not on locking merchants into a pricing tier they can't easily leave.
Method note
Every figure above comes from the vendor's own changelog, pricing page, or blog post, not a summary written by someone else. Pricing for DOKU and HitPay reflects each company's published fee schedule as of this week; KiotViet's tier prices have been unchanged since 1 May 2025. Currency conversions to USD are approximate and will drift with the exchange rate, so treat them as a rough guide, not an invoice. If you spot a change we missed, that's usually because the vendor buried it in a release note instead of an actual announcement, which is most of them.
