Serlzo vs Bumbi: which WhatsApp automation actually sells more?
On this page
Bumbi is a platform for creators who sell digital products: ebooks, courses, templates and presets. The account that sends the WhatsApp follow-up also takes the payment and delivers the file. New here? Read what Bumbi is and how it works.
WhatsApp follow-up
WhatsApp follow-up automation from your own number
The painA lead asks for the price, you reply three hours late, and they have bought from someone else.
Bumbi sends WhatsApp follow-ups from your own number: link it once in Settings by scanning a code, the way you link WhatsApp Web, and every message goes out as you. Build the sequence once: a welcome the minute someone joins your list, a nudge the next day with their first name dropped in, and a thank-you with the download link after a purchase. Leads and buyers each get their own sequence, and a lead's sequence stops the moment they buy. WhatsApp is on Starter and up; Free includes 300 messages. See the WhatsApp automations release notes.
Follow up every lead, as yourself, without typing.
Groups
WhatsApp group automation with one join link that never dies
The painYour group hits its limit mid-launch and the join link you shared everywhere is now a dead end.
Bumbi gives a group funnel one stable join link: one active group stays open, a reserve group opens before it fills, and new joiners move across without you touching the link. Scheduled messages reach every group at once, and a step can close posting while your class plays. Starter 1 funnel, Growth 3, Elite unlimited; read the WhatsApp Group Automation release notes.
One link, as many groups as you need.
Paid class
Sell seats in a paid WhatsApp class
The painYou run a paid class in a WhatsApp group, then spend the evening checking receipts and adding people by hand.
Bumbi sells the seat as a product. A buyer pays at your checkout and lands on a page with the group join link, so only paid students get in and you never add anyone by hand. The link stays the same and opens a fresh group when one is full. Read how to run a paid WhatsApp class.
Paid buyers join on their own; nobody else gets the link.
Checkout
Checkout in the buyer's own currency, with coded withdrawals
The painThe follow-up worked, the buyer is ready, and the payment page is where you lose them.
Bumbi gives every product one checkout link, like yourname.bumbi.io/buy/your-product, and the page confirms the payment on its own, built for 99.9% payment uptime. Buyers in other countries see and pay in their own currency where supported. Every withdrawal from your Wallet is confirmed with an emailed 6-digit code. Checkout and the wallet are on the Free plan, free forever.
The message and the money live in one account.
Delivery
Automatic delivery and a buyer library
The painA buyer pays at 11 pm and messages you at 11:05 for the file.
Bumbi delivers the file by email the moment payment is confirmed, and your WhatsApp thank-you can carry the link too. Upload a PDF, Word, Excel, EPUB or CSV file up to 20 MB, or add an external link. Later the buyer signs in at bumbi.io/access with an emailed code and finds everything they bought from any Bumbi seller.
Deliver once, correctly, forever.
Courses and memberships
Courses, memberships, subscriptions and coaching
The painYou have more than a PDF to sell, and a WhatsApp group is not a classroom.
Bumbi hosts your lessons, memberships and coaching next to your downloads. A course is sections and lessons: video, text, quiz, assignment, download or live session, with drip, a pass mark and a certificate. Memberships and subscriptions renew monthly or yearly, with reminders first. For coaching, set your hours and the buyer books a slot right after paying. Free includes 1 of each; Growth and Elite have no limit (plan limits).
Interview Prep Masterclass
Lessons, recurring money and booked calls, no second tool.
Bumps and recovery
Order bumps and abandoned checkout recovery
The painMost people who start checkout never pay; the rest buy one thing.
Bumbi adds an order bump above the pay button: one extra product, ticked in one click and paid in the same payment. For the people who started checkout and did not pay, Bumbi sends three reminder emails from your name over the next day, each with one button back to the same checkout, on every plan.
Interview Prep Guide, $15
Almost-buyers and fresh buyers are your easiest sales.
Affiliates
Affiliates and verified reviews on every plan
The painYou are the only one selling, and your page has no proof.
Bumbi lets other people sell your product for a share of each sale. Switch on Affiliates on any product, choose what each affiliate earns, and they get a portal with tracked links. After each purchase, Bumbi emails the buyer for a Verified purchase review that shows on your page. More: how the affiliate checkout link works.
Other audiences sell for you; other buyers vouch for you.
Webinars
Automated webinars with WhatsApp reminders
The painA WhatsApp broadcast cannot explain a $150 course.
Bumbi runs your recording as scheduled live sessions with registration, email and WhatsApp reminders, a room with chat, a countdown offer linked to your checkout, and a replay. Webinars are on Growth and up; a VSL offer starts on Starter. Read how to sell with webinars and how to add an offer to your webinar room.
Let a recording sell your expensive product every day.
Pages, tracking, Teams
Landing pages, ad tracking, Teams and direct WhatsApp support
The painYou run ads and cannot tell which one brought the sale.
Bumbi hosts your storefront and landing pages, from a template or from HTML that Claude or ChatGPT wrote for you. Paste your Meta Pixel ID in Integrations and Bumbi adds it to your pages and checkout, no code. On Growth and Elite, add an assistant with the access you choose; the support bubble opens a WhatsApp chat with a real person on the Bumbi team. Setup: how to build a landing page in Bumbi and how to add retargeting pixels to your funnel.
Build it, track it, share the work.
