Odoo Website Promo Bars Without Custom Theme Code Every Black Friday

Originally published at hexalian.com/store/hex_website_announcement_bar.

TL;DR — Marketing wants a sitewide promo strip with countdown and analytics. Theme hacks break on every Odoo upgrade. Website Promo Banner & Announcement Bar is a standalone Odoo 17–19 app with 30 templates, live preview, and click tracking. Already sold on Odoo Apps (France v19, Thailand v18).

The conversation that happens every October

Your marketing lead opens Slack:

"Can we add a sticky Black Friday banner with a countdown — today?"

If you run Odoo eCommerce or a B2B portal, you know what comes next:

Someone edits the website theme QWeb
Countdown JavaScript gets copy-pasted from last year
It works in staging
Odoo 18 → 19 upgrade breaks the override
February: "Why is the summer sale bar still showing?"

That is not a marketing problem. It is an architecture problem.

We built Website Promo Banner & Announcement Bar so merchandising teams can publish promos from the Odoo backend — without opening the theme repo every campaign season.

It is already selling on the Odoo Apps Store — shops in France (Odoo 19) and Thailand (Odoo 18) bought it for real production use, not a demo database.

Theme hack vs dedicated module

	Theme QWeb hack	Website Promo Banner module
Time to first bar	Hours (dev)	~15 minutes (marketing)
Survives Odoo upgrade	Often breaks	Maintained module path
Countdown auto-hide	Custom JS each year	Built-in
Click analytics	Usually none	Views + clicks per bar
Multiple campaigns	Fragile	Multi-bar + scheduling
Who maintains it	Developer queue	Marketing + settings screen

Rule of thumb: If marketing asks for promo changes more than twice a year, a module pays for itself on the first avoided dev sprint.

What you get (without touching the theme)

Merchandising features

Sticky top bar — promo stays visible while scrolling
Live countdown timer — bar auto-hides when the offer ends (real JavaScript timer, not a static date string)
Pulse animation — urgency without custom CSS on every campaign
30 ready-to-use templates — B2B notices, flash sales, free-shipping strips, trade-show banners
Live preview in the backend — see exact colors, fonts, and layout before publish
Multi-bar stacking — run prioritized campaigns; no arbitrary "one default template" limit

Targeting and control

Visitor targeting — first-time vs returning visitors (lightweight cookies)
URL / page filtering — show bars only on /shop, checkout, or specific landing pages
Schedule windows — start/end datetime per campaign
Multi-company — separate bars per company on shared infrastructure

Analytics (the part theme hacks never have)

Views and clicks per bar — read-only stats in the backend
Compare campaigns: which copy drove clicks before you rewrite the whole shop

Standalone app with its own top-level menu — not buried three clicks deep inside Website settings.

Who this is for

eCommerce shops (Odoo 17–19)

Black Friday, summer sale, free shipping over €X, last-chance checkout reminders — publish from the backend the same day marketing decides the offer.

B2B portals

Payment terms updates, trade-show announcements, catalog maintenance notices — professional strips without a front-end contractor.

Odoo partners and agencies

Deploy the same capability across client sites. Full Python/XML source, no license server, no subscription. One upgrade path for every storefront you maintain.

15-minute setup (first campaign)

Install from Odoo Apps (search Website Announcement Bar, publisher Hexalian) — or download the ZIP for your Odoo version from Gumroad / hexalian.com/store
Open Website Announcement Bar from the main menu
Pick a template (Flash Sale, Free Shipping, B2B Notice, …)
Set colors, copy, CTA link, schedule, and countdown deadline
Enable the template — check live preview, then verify on the public site

Works on Odoo 17.0, 18.0, and 19.0 — Community and Enterprise.

Before production: test on staging first (same advice we ship in the module docs). Toggle master enable/disable globally when you need a hard kill switch.

Pricing and delivery

One-time purchase — no monthly fee, no seat limits
Full source code — OPL-1, standard Odoo module layout
Pick your Odoo version — separate SKUs for 17 / 18 / 19 on Gumroad; Odoo Apps listing per version

FAQ

Does this replace my website theme?

No. It injects announcement bars at the site header level. Your theme stays intact.

Can I run multiple bars at once?

Yes — stack by sequence priority; enable/disable per template.

GDPR / cookies?

Visitor targeting uses lightweight cookies. Strict cookie controls are configurable from settings (review with your DPO for EU shops).

Custom HTML/CSS?

Advanced mode supports custom HTML and scoped CSS (.hex-announcement-bar prefix) for agencies that need brand-perfect layouts.

What if I only need one bar once a year?

Still cheaper than a developer day every October — and you keep analytics for next year's campaign.

Going live on Odoo? (cross-sell)

Promo bars drive clicks. Production go-live is a different problem — backups nobody tested, staging that does not match prod, email that only worked in dev.
