SEA SaaS Tracker: 2026-09-03

If you're a Bangkok bookkeeping firm billing US-entity clients through Xero, or the one person in a Ho Chi Minh City shop who owns the WhatsApp inbox, vendor changelogs aren't background reading. They're the thing that decides whether next month's invoice makes sense. Here's what actually changed for Xero, Notion, and Sleekflow in the last cycle, with a source on every line.

Xero

Xero's US subscription prices go up on 2026-10-01. Early plan: $25/mo to $27/mo, up $2. Growing plan: $55/mo to $59/mo, up $4. Established plan: $90/mo to $97/mo, up $7. That's a 7-8% increase across the board, and the multi-organization discount disappears for any new subscription signed after that date — existing discounts and promo codes ride out to their own expiration.

Xero sent the price-change notice to customers and partners in late July, so this isn't a surprise sprung on renewal day. The new $97/mo Established price works out to roughly THB 3,492 in Bangkok or PHP 5,626 in Manila at today's rates. The smaller increases convert too: the $2 Early-plan bump is about MYR 9, and the $4 Growing-plan bump lands near SGD 5.40. None of that sounds dramatic on its own.

The number to watch is the multiple, not the single plan. A $7/mo increase on Established is $84 a year per subscription, so anyone paying for a subscription per client file multiplies that by every file they carry, and the increase lands before any of their own rates change. No new Shopee, TikTok Shop, VietQR, PromptPay, or GCash integration shipped for Xero in this window.

Notion

Notion's Developer Platform — Workers, the External Agents API, Notion CLI, Agent SDK, webhook triggers, and a Markdown API — shipped back on 2026-05-13. That's outside this cycle's window, but you need it as context for what happened next: on 2026-08-11, the free period for Workers ended. Worker runs now draw down Notion credits instead of running at no cost. The CLI itself stays free on every plan tier; deploying and managing Workers is still limited to Business and Enterprise.

Two more things landed inside the window. On 2026-08-14, a model picker shipped for harder tasks — a shortlist of models, each with a scorecard for speed, intelligence, and cost, plus the ability to pin favorites and set an effort level. On 2026-08-19, a Developer section arrived in the workspace sidebar (Settings > Developer > Enable developer features). It now consolidates Worker management, connections, personal access tokens, and deployed-Worker logs, plus a developer bar for copying page, database, block, workspace, and user IDs.

Charging for Worker compute was always the likely end state — nobody runs AI agents at scale for free indefinitely. The part worth flagging is the delivery: a change to what you are billed for arrived in a release note rather than a billing email, which is how an ops team mid-renewal finds out late. No pricing-tier change touched Notion's core per-seat plans (Free, Plus, Business, Enterprise) in this window; the credits shift applies only to Worker usage.

Sleekflow

Meta's WhatsApp Business API pricing changes take effect 2026-10-01, and they flow straight through to every Sleekflow customer on the WhatsApp Business Platform. Two things change. Service messages — free-form replies sent inside the 24-hour customer-service window — become billable for the first time since they went free in late 2024. Utility-template messages lose their in-window fee exemption too, so they're now billed whether they go out inside or outside that 24-hour window. Both message types get charged individually at a flat per-message rate, with no volume discount.

How much this stings depends entirely on how you use WhatsApp. An account running mostly one-way broadcast campaigns sees a small bump. It's the high-volume support and sales teams that feel this. A Ho Chi Minh City retailer fielding a few hundred WhatsApp support replies a day inside the service window will notice this. A Jakarta brand sending one weekly broadcast promo barely will.

If that describes your support queue, the invoice worth reading is the current one, not the October 2nd one. A support queue that used to run on free service-window replies is about to carry a real per-message cost, and finding that out after the bill lands is the expensive way to learn it. This is a platform-level Meta change, not a Sleekflow price hike, but Sleekflow customers are the ones who'll answer for it. No Sleekflow-specific tier change or new Shopee, TikTok Shop, VietQR, PromptPay, or GCash integration shipped in this window.

Not confirmed this cycle

No exact-dollar pricing-tier change turned up for Notion's core plans or for Sleekflow's own subscription tiers this window. Both of the pricing stories above start one level up — Notion's Worker credits and Meta's platform-wide WhatsApp fees — rather than a per-seat list-price move. And across Xero, Notion, and Sleekflow alike, still no new Shopee, TikTok Shop, VietQR, PromptPay, or GCash integration confirmed.
